Abstract: An OLED display including a display panel and a color-correction component is described. A plurality of comparative display panels otherwise equivalent to the display panel but having one or more different optical thicknesses of OLED layers have a maximum white-point color shift from 0 to 45 degrees of WPCS C 45 and a white-point axial efficiency of WPAE C . The plurality of comparative display panels defines a performance curve along a boundary of performance points. The OLED display and the display panel have respective maximum white- point color shifts from 0 to 45 degrees of WPCS 45 and WPCS 0 45 and respective white-point axial efficiencies of WPAE and WPAE 0 . WPCS 0 45 and WPAE 0 defines a performance point of the display panel to the right of the performance curve and WPCS 45 and WPAE defines a performance point of the OLED display above or to the left of the performance curve. Methods of making the OLED display are described.

Abstract: A lightguide having opposing first and second major surfaces where the first major surface includes a plurality of extended features and a plurality of discrete features is described. The lightguide has a viewable area having a length at least 100 times a thickness of the lightguide. The extended features extend in a first in-plane direction across at least 90 percent of the length L of the viewable area. The discrete features are spaced apart along the length and width of the viewable area. The discrete features may be disposed in spaces between the extended features. The discrete features may have faces extending between and connecting adjacent extended features.

Abstract: An optical system includes a backlight configured to emit light from an emission surface thereof, and a front reflector. The backlight includes at least one light source configured to emit a first light having at least a first wavelength. The front reflector is disposed on a back reflector and defines a recycling optical cavity therebetween. The front reflector defines at least one opening therein. When a test material is disposed in the recycling optical cavity, the test material is configured to emit a second light having at least a second wavelength in response to a stimulus. The emitted second light exits the optical system through the at least one opening of the front reflector after being recycled in the recycling optical cavity. The recycling affects an optical intensity of the exiting light.

Abstract: An optical construction can include a lens layer including microlenses formed on a substrate and at least one light absorbing optical cavity disposed on a substrate side of the lens layer. Each light absorbing optical cavity has an average thickness of less than about 300 nm and includes an optically transparent middle layer disposed between light absorbing first and second end layers. Each of the first and second end layers, but not the middle layer, defines a plurality of through openings therein aligned in a one-to-one correspondence with the microlenses. The optical construction can include an optically transparent spacer layer disposed between two light absorbing optical cavities. An optical system includes the optical construction and a refractive component including at least one prism film.

Abstract: A display system for sensing a finger of a user applied to the display system includes a display panel; a sensor for sensing the finger; a sensing light source configured to emit a first light having a first wavelength W1; and a reflective polarizer disposed between the display panel and the sensor. For a substantially normally incident light, an optical transmittance of the reflective polarizer versus wavelength for a first polarization state has a band edge such that for a first wavelength range extending from a smaller wavelength L1 to a greater wavelength L2 and including W1, where 30 nm ≤ L2 – L1 ≤ 50 nm and L1 is greater than and within about 20 nm of a wavelength L3 corresponding to an optical transmittance of about 50% along the band edge, the optical transmittance has an average of greater than about 75%.
